Denominations and Serial Numbers

I have a list of my Savings Bonds that includes serial numbers, dates, and registrations, but I forgot to write down the denominations. Can I tell the denominations from the letter in the serial numbers? Tom's response My contacts at the Bureau of Public Debt tell me that the prefixes hold regardless of series and are:

• L - $50
• K - $75
• C - $100
• R - $200
• D - $500
• M - $1,000
• V - $5,000
• X - $10,000
